[0030] For example, Figures 1 to 6As shown, in this embodiment, a bidirectional current converter includes a bidirectional current converter unit 1, a cable connection port one 2 and a cable connection port two 3 arranged at the front end of the bidirectional current converter unit 1, and a mounting base plate 4 arranged below the bidirectional current converter unit 1. Two sets of guide sliding grooves 6 are formed at the top end of the mounting base plate 4, and two sets of guide sliding rails 7 are fixed to the bottom end of the bidirectional current converter unit 1. Both sets of guide sliding rails 7 can be inserted into the two sets of guide sliding grooves 6 on the mounting base plate 4. A fixed sleeve 8 is mounted on the front side of the mounting base plate 4, a threaded sleeve 9 is fixed to the fixed sleeve 8, a threaded rod 10 is threadedly connected in the threaded sleeve 9, a top plate 11 is rotatably connected to the rear end of the threaded rod 10, and a handle 12 is fixed to the front end of the threaded rod 10. A plurality of anti-slip grooves are formed on the outer wall of the handle 12 at equal intervals along the axis of the handle 12. Through this design, the friction between the handle 12 and the user's hand can be effectively increased, thereby facilitating the user to effectively hold and twist the handle 12. A mounting seat 13 is fixed to the front end of the outer wall of the bidirectional current converter unit 1, and the top plate 11 is fixedly connected to the mounting seat 13 by screws. An interface protection kit is arranged on the right side of the mounting base plate 4.

[0031] By installing the mounting base plate 4 at the bottom end of the bidirectional current converter unit 1, the bidirectional current converter unit 1 can drive the mounting base plate 4 to be installed on the bracket. When the position of the bidirectional current converter unit 1 needs to be adjusted, the threaded rod 10 on the mounting base plate 4 can be rotated. The threaded rod 10 can drive the bidirectional current converter unit 1 to be adjusted in position in the horizontal direction under the action of the threads, and the position of the bidirectional current converter unit 1 can be accurately positioned. This not only ensures the stability of the bidirectional current converter unit 1 during installation, but also quickly adjusts the position of the bidirectional current converter unit 1, effectively reduces the difficulty of adjusting the position of the bidirectional current converter unit 1, and improves the convenience of installing the bidirectional current converter unit 1.

[0032] In other embodiments, the interface protection kit includes a sliding sleeve 14 fixed to the outer wall of the right side of the mounting base plate 4, a sliding block 15 slidingly connected in the sliding sleeve 14, a protective sleeve 16 fixed to the top end of the sliding block 15, and two sets of through grooves 17 formed at the front end of the protective sleeve 16. Widened grooves 18 are formed in the middle of the two sets of through grooves 17, and a movable sealing assembly is arranged at the middle of the front end of the protective sleeve 16.

[0033] When the cable connection port one 2 and the cable connection port two 3 are externally connected with the pipeline, the protective sleeve 16 can be pushed to move the slider 15 along the sleeve 14, and the two groups of through slots 17 on the protective sleeve 16 are moved to the outside of the connection between the cable connection port one 2 and the cable connection port two 3, thereby forming protection for the outside of the connection between the cable connection port one 2 and the cable connection port two 3, effectively preventing external objects from touching the connection between the cable connection port one 2 and the cable connection port two 3, and preventing the connection from loosening and being damaged, thereby ensuring that the equipment can operate normally for a long time.

[0034] In other embodiments, the movable sealing assembly includes a guide rod 19 arranged in the middle of the front end of the protective sleeve 16, two groups of guide blocks 20 slidably connected to the outside of the guide rod 19, sealing side plates 21 fixed to the outside of the two groups of guide blocks 20, and a reset spring 23 wound around the outside of the guide rod 19. The rear end of each of the two groups of sealing side plates 21 is glued with a sealing rubber sleeve. This design can effectively reduce the gap between the sealing side plates 21 and the openings of the front ends of the through slots 17, so that the sealing side plates 21 can effectively seal the openings of the front ends of the through slots 17. The two ends of the guide rod 19 are respectively connected to the opposite end walls of the two groups of guide blocks 20. The two groups of guide blocks 20 are elastically connected to each other through the guide rod 19, so that the guide rod 19 can continuously apply opposite forces to the two groups of guide blocks 20, and the two groups of guide blocks 20 can quickly move the sealing side plates 21 to the openings of the front ends of the two groups of through slots 17 on the protective sleeve 16. The front end of each of the two groups of sealing side plates 21 is fixed with a push plate 22.

[0035] When the protective sleeve 16 is moved to the outside of the cable connection port one 2 and the cable connection port two 3, and the pipeline connected to the outside of the cable connection port one 2 and the cable connection port two 3 is placed in the through slots 17 on the protective sleeve 16, the reset spring 23 outside the guide rod 19 can release the elastic force to push the two groups of guide blocks 20 to move backward, so that the sealing side plates 21 on the two groups of guide blocks 20 can quickly move to the openings of the front ends of the two groups of through slots 17 on the protective sleeve 16, and the two groups of sealing side plates 21 can seal the openings of the two groups of through slots 17, thereby effectively preventing external objects from entering the through slots 17 from the openings of the through slots 17, ensuring the cleanliness of the through slots 17, and facilitating the later maintenance of the connection between the cable connection port one 2 and the cable connection port two 3.

[0036] As shown in FIG. 1, Figure 3 The installation plate 5 is fixedly installed on the four corners of the installation base plate 4, and a strip-shaped slot is formed in the installation plate 5.

[0037] Through the design, four groups of mounting plates 5 on the mounting base plate 4 can be quickly mounted on the bracket through bolts, and the bolts can be quickly adjusted in the strip-shaped slot to adjust the mounting position of the mounting base plate 4.

[0038] As shown in Figure 6 The size of the widened slot 18 corresponds to the size of the connecting sleeve head outside the cable connecting port one 2 and the cable connecting port two 3.

[0039] Through the design, when the external pipeline is installed outside the cable connecting port one 2 and the cable connecting port two 3 through the connecting sleeve head, it is ensured that the widened slot 18 inside the through slot 17 can be smoothly moved to the connecting sleeve head outside the cable connecting port one 2 and the cable connecting port two 3.
